APPARATUS FOR TRUING EUR-FLANGE. SEATS.

Application filed May 2,

,t-ruing hub flange seats, and the object of the invention is theconstruction of a simple and efficient apparatus for truing the hubflange seat of an. automobile wheel.

My apparatus can be operated by hand or power; it feeds automaticallyacross the face of the wheel leaving the face true with the outer rim.

With the foregoing and other objects in view, my invention comprisescertain novel combinations, constructions and arrangements of parts aswill be hereinafter described, illustrated in the accompanying drawings,and more particularly pointed out in the appended claims.

In the drawings:

Figure 1 is a top plan view of an apparatus constructed in accordancewith the present invention, while Figure 2 is a view in side elevationof the same.

Figure 3 is a top plan view of the supporting frame.

Figure 4 is an enlarged, fragmentary view, partly in section and, partlyin side elevation, of the gauge device.

Figure 5 is a sectional view, taken on line 5-5, Fig. 1.

Figure 6 is a sectional view, taken on line 66, Fig. 4, and looking inthe direction of the arrows.

Figure 7 is a sectional view, taken on line 7-7, Fig. 4, and looking inthe direction of the arrows.

Figure 8 is a perspective view of the sleeve.

Referring to the drawings by numerals, 1 designates the supporting framewhich comprises a body 2, from which extend integral arms 3. Formed uponeach arm 3 is a depending lug 4 forming a supporting foot. Slidablymounted on each arm 3 is a substantially rectangular bracket 5, whichbracket 5 has a head 6. Threaded into head dis a screw 7. The rim 8 ofwheel 9 is placed upon the supporting frame, then.

the screws 7 are screwed against the outer face of the rim tightlyclamping the rim 8 upon the arm 3 of the supporting frame, Figs. 1 and5.

A spindle 10 extends through the body 2, the extreme lower end of thespindle being threaded into nut 11; the spindle is provided with a hubportion 12 that rests, at its lower end, upon body 2, and on the spindleand immediately above, and in engagement with hub portion 12, is sleeve13. The sleeve 13 is provided with a notch 14 that straddles spur plate15. Spur plate 15 is provided with a spur 16 that engages the outer faceof sleeve 13. Sleeve 13 is provided with a spur 17 that is adapted to beengaged by the star wheel 18 secured to the inner end of gauge screw 19.r

The gauging device 20 is revolublymounted upon spindle 10 and includeshollow body 21, which body 21 is provided with a detachable handle 22that is heldupon the body by screw23. Handle '22 is provided with a grip24. A shaft 25 has its inner end integral with the hollow body 21, andits outer end engages the lower end of angle brace '26. A. screw 27extends through brace'26 into shaft 25 holding the brace securely to theouter end of the shaft. The upper end of brace 26 is secured to thehollow body 21, at 27, Fig. 2. The extreme lower end of brace 26projects below shaft 25, and gauge screw 19 is revolubly mounted on thebrace; its inner end 28 projects a slight distance into the hollow body21, with the star wheel 18 bearing against the hollow body 21.

A marker device 29 is provided, comprising body 30 slidably mounted onshaft 25, with screw 19 extending therethrough (Fig. 6) so that when theoperator rotates screw 19, the body 30 will be adjusted longitudinallyof shaft 25. A marker pin 31, which has its lower end sharpened andconstitutes a cutter is slidably mounted in a vertical plane upon body30 and is held in an adjusted position by screw 32.

When this device is in use the wheel which has become warped has its hubremoved and the wheel is then put in place as shown in Figures 1 and 2,the rim being clamped tightly against the arms 3 by the set screws 7.The sleeve 21 will now be placed upon the stem or spindle 10 and theshaft 25 and screw 19 will extend radially above the contacting innerend portions of the spokes.

One or more of the sleeves 13 will of course, be put in place ifnecessary and the cutter 29 adjusted so that as it moves along the shaft25 the contacting portions of the spokes will be trimmed in the samemanner that a lathe would operate. In order to perform the cutting thesleeve is rotated by means of the handle 22 and as it rotates the starwheel 18 will strike the finger 17 thus causing the screw to be rotatedand the carrier 30 moved outwardly along the shaft. After one completeout has been made the carrier will be returned to its original positionnear the sleeve, the cutter lowered and the operation repeated until thewarped portion is entirely cut away. After the proper amount of cuttinghas been performed the sleeve will be lifted from the spindle and thescrews 7 loosened so that the wheel can be removed and the hub put backin place. The hub will now fit properly and the wheel will betrue. If itis only desired to test the wheel to see if it is true the pin would notbe initially set low enough to make a cut and the device would thenserve only as a gauge with the pin as a gauge pin to indicate if cuttingis necessary.

My apparatus is especially built for the purpose of truing up a centercircle, on an automobile wheel. This apparatus will eliminate wear ontires, allow the driver to keep his car in perfect alinement. The deviceis so simple it can be installed in the smallest repair shops.Heretofore, one had to lay up his automobile, andremove the warpedWheel, ship it to the nearest city to have it trued' up in a lathe. Thisapparatus eliminates all that time and expense.

What I claim is:

1. In an apparatus of the class described, the combination with a frame,of a spindle extending axially of said frame and provided near its lowerend with a hub portion resting upon said frame, said spindle providedwith a portion extending through said frame, a spur plate attached tosaid hub portion, a sleeve provided with a spur resting on said hubportion and engaging said spur plate, a hollow body on said spindle andengaging said sleeve, said hollow body provided with an operating devicein eluding an adjusting screw having a spur wheel, and said spurwheeladapted to engage the spur of said sleeve.

2. In an apparatus of the class described, a wheel support, a spindleextending from said wheel support, a sleeve fitting upon said spindleand held against rotation, a spur extending from said sleeve, a hollowbody rotatable upon said spindle and resting upon said sleeve, andoperating means carried by said body and provided with an adjustingscrew having a spur wheel adapted to be engaged by the spur of saidsleeve and turned thereby as the body is rotated upon said spindle.

V In testimony whereof I hereunto afiix my signature.
